Dunno if someone will do it but all in all, she is promoting the "ZOOM A1X FOUR". A bit like what you can use with a guitar, this piece of technology (according to her) is brand new because it supports saxophone (among other instruments like violin, trumpet, ...). You plug a microphone, which you usually use, to it and it allows the musician to apply effects (presets or personalized) to your notes and loop some melody (like a looping pedal for guitars). She says it's awesome and hope that everyone is as excited as her for discovering this.
